invention has for its object a novel construction of means 'forresisting end thrust' in bearin -es ecially bearings such as shown inTgsnite States Patent No. 713,058, granted Novenber 11, 1902, myinvention beingalso, it will be understood, aplicable to any form ofbearing wherein it is esired to resist successfully the -wear and shockdue to end thrust in opposite directions.

granted December 25, 1900, to J. A. Perkins. The bx'extensionE isclosedby aI cap E.

I believe that I am the first to use ahub or box with a trackdisconnected from the axle and restrained by or through the b'ox frommoving longitudinally of the axis of the axle and to employ with saidtrack antifriction means disconnected from the hub or box and sustainedby or through the axle, said anti-4 rictionrnean's coacting with theopposite sides of said track.`

Having described my invention, what claim, and desire to secure byLetters Patent, is-

1. In a'rollerbearing, of the class having bearing-rollers interposedbetween the box and axle, an axle having a tenon at its end,

a track disconnected from the hub or -box washers having each anvannular grooveantifriction means in each groove, said antifriction meanscontacting with the oppositev sides of said track.'

2. In a bearing, an axle having a tenon, a hub or box, a nut on saidtenon, and a track sustained by said nut, combined with two end-thrustwashers having each an annular land surrounding said tenon, twoend-thrust groove and sustained by said box, antifriction. l meansrecelved 1n said grooves and contacting with opposite sidesof saidtrack.

3. I n a roller-bearing, a-hub or box, an axle having a tenon, at one end, a nut mounted on'said tenon, a track sustainedbysaid nut, and twoend-thrust washers each having an annular groove, a series of balls ineach of said grooves, said balls contacting with the track sustained bsaid nut. i

4. In a `rollercaring, a .hub orbox, an axle having a tenon at Vone end,a nut mount-` ed'on said tenon, a track'sustainedy'said nut,l and twoend-thrust 'washers each having roo an annular groove, a set off'balls'in each of said grooves, said balls contactin with said trackatits opposite sides at di erent distances from the outer edge of thetrack.

5. In -a roller-bearing, an axle having' a tenon at its end, a boxinclosing said axle, a

nuasurrsnding Said tw, nutgbsa l iro provided with a ierrule, a tracksurrounding said nut and held in position thereon between a shoulder ofsaid nut and said ferrule, combined with two endthrust 'washers eachhaving an annular groove, said washers being sustained in said box, anda set of balls located in each of said grooves, said balls contactingwith the opposite sides of said track.

6. ln a bearing, an axle having a tenon, a hub or box, a track and a nutholding said track in position upon the tenen, combined with twoend-thrust washers sustained by said box, and antifriction means uponopposite sides of 'said track contacting therewith and with saidWashers. .v

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
